Overview

Type 4 Long-Grain Copper allows for a smoother and clearer sound than cables using typical OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metallurgical industry specification regarding “loss” without any concern for distortion. LGC has fewer oxides in the conductor material, fewer impurities, fewer grain boundaries, and significantly better performance.

All four conductors in Type 4 are solid. The electrical and magnetic interaction between the strands of a conventional cable is the most significant source of distortion, often causing a somewhat harsh, dirty, and confused sound.

Solid conductors are the most important ingredients enabling the very clear sound of Type 4. Whether a conductor is solid or stranded, skin effect is a prime distortion mechanism in speaker cables. Type 4 simply keeps this effect out of the audio range by using conductor sizes below the threshold of audible distortion.

Dissipation System

The two negative conductors in Type 4 are insulated with partially conductive carbon-loaded polyethylene. This remarkable material damps radio-frequency waste from being reinjected into the amplifier. The sonic benefit is the same reduction of “hash” and better dimensionality that comes when RF waste is reduced in an audio circuit. Type 4 uses nitrogen-injected polyethylene foam insulation on its positive conductors because air absorbs almost no energy, and polyethylene is low-loss and has a benign distortion profile.
